In 1955 a series of 14 nuclear test explosions known as "Operation Teacup" were set off in the Nevada desert at Yucca Flat.
The most memorable part of the tests were the purpose-built homes and other structures set at varying distances from the blasts to test the impact and effects of the explosions, known collectively as "Survival Town" – or, slightly less optimistically, "Doom Town."
The most disturbing element of the fake town was its citizens: the homes were populated by 1950s picture-perfect mannequin families, bravely facing their imminent doom going about their daily routines in dapper outfits. Thousands of spectators watched the blasts from what was thought to be a safe distance. (Note: it was not a safe distance.)
Public tours are available.
